Im by no means an expert but I am trying to obtain advice on why my hvac system for home pulls in outside odors.
I live about a mile and half from a very large cow feed company. It produces nasty odors. When my heat kicks on the smell immediately fills the house. My understanding about the ac system is, it just recirculates the air inside the house and doesnt draw air from outside.
Could I have a tear or in my ductwork? This is 7 month old house and I dont have the aluminum type duct work.(hopefully you know what I mean).
Thanks for the help.
